RE: Charging Noise
My Fluence is on charge right now and I have tried to hear any noises at all. ... none that I can hear, at all.
If I have been driving it fast and recharge straight away, the battery cooling fan will run for an hour or two, but it is a fairly quiet not-unpleasant noise that I can't hear indoors.
A high pitched whine from charging that can be heard indoors and that neighbours actually complain about is an EV not fit for its purpose, IMHO. It has to be silent during night charging, for obvious reasons.
I've heard the Zoe actually uses the motor as a transformer during charging. Is that something to do with the noise, I wonder?
Irrespective of whether it is 'normal', I'd tell the dealer it is not good enough.
